The light source (101) is configured to provide, in operation a light output (111). The first reflector (102) comprising a first reflective surface (121), and the second reflector (103) comprising a second reflective surface (131). The first reflective surface (121) is configured face the second reflective surface (122). The light source (101) is configured to emit the light output (111) towards the second reflective surface (131). The second reflective surface (131) comprises a plurality of sections (133), each section (133) comprising a first section surface (134) that faces away from a center axis (001) of the light source (101) and a second section surface (135) that faces towards the center axis (001).

摘要： A car door grommet plug has a holder, a light-emitting unit located in the holder, a top cap mounted on the top of the holder and restraining the light-emitting unit and a shell located in the holder. The light-emitting unit is electrically connected to a power supply. When the opening of car door is sensed, the light-emitting unit emits light outwards, providing a caution signal for vehicles or pedestrians coming from behind.

摘要： An illuminating device includes an LED element, and a reflecting surface arranged in front of the LED. The reflecting surface includes a second reflecting surface formed in a substantially conical face shape with an apex at an intersection between an optical axis of the LED and the mirror reflecting surface and a conical side wall bulged inward, and a first reflecting surface formed as a concave reflecting surface recessed forward and having a first focal point disposed at or near the light emitting element and a second focal point disposed on the optical axis between the first focal point and the intersection. A housing including a plurality of reflective surfaces might also be included, with the illumination device positioned within.

摘要： Optical lens (3) for a LED comprising a lens body (10) having: —a light-entering section (1), where light from the LED enters the lens (3), having a cross-sectional dimension (D2) and recessed to accommodate a LED; —a light-emitting front face (2); —a frusto-conical shape (4), extending along a central axis between the light-entering section (1) and the light-emitting front face (2), the outer surface of which incorporating a plurality of densely-distributed convex facets (24); —a height (H) along said central axis; —a cross-sectional width (D1) at the level of the light-emitting front face (2). This optical lens enhances light utilization efficiency, avoids creating spots with chromatic aberration hence greatly improves color rendering.
